Should agent identities be governed inside the same lifecycle as human users and service accounts?

Yes, but not with the same assumptions. Agents need the same lifecycle disciplines, including review and offboarding, yet they must be governed through behaviour-aware discovery and durable ownership because their access patterns can change faster than human-centric review cycles.

Should Agent Identities Be Governed in the Same Lifecycle as Human Users and Service Accounts?

Agent identities should usually sit in the same governance system, but not as a copy of human-user administration. They need comparable lifecycle controls for provisioning, review, rotation, and offboarding, while also needing tighter behavioural visibility because their tool use, scope, and frequency can shift faster than human-centric review cycles. The control plane should treat them as first-class identities with different operating assumptions.

What Changes When Agents Are Put Into the Same Lifecycle Model?

The practical question is not whether agents belong in identity governance, but which parts of the lifecycle can be shared and which parts need agent-specific handling. Human users, service accounts, and agents all need ownership, inventory, access review, and revocation. What changes is the evidence you trust: humans are usually governed through role, manager, and employment status; agents need behavioural signals, dependency mapping, and explicit business ownership for the automations they run.

That difference matters because agents can accumulate access through drift, reuse, hidden dependencies, or unattended integrations. A lifecycle process that only asks, “Is the account still assigned?” will miss whether the agent still needs the same tools, same tokens, same environment, or same delegated authority. In NHI practice, lifecycle control is only effective when it reaches the credential, the workload, and the decision path together.

For a broader NHI lifecycle view, Ultimate Guide to NHIs is the best starting point, and the lifecycle detail in NHI Lifecycle Management Guide is especially useful where provisioning, rotation, offboarding, and ownership need to be operationalised.

Why Behaviour-Aware Discovery and Durable Ownership Matter

Agent governance breaks down when ownership is implicit or when inventory is built only from static account records. Discovery has to follow the actual execution surface, meaning the agent, its credentials, the tools it can call, and the systems it can affect. Durable ownership then ensures someone remains accountable when the original developer, prompt owner, or automation sponsor changes.

Behaviour-aware review is the missing layer for many teams. An agent can begin with narrow access and later expand through added tools, inherited permissions, reused secrets, or new workflows. If review cadence is slower than that change rate, the account may still look valid even though its effective blast radius has grown. That is why lifecycle management for agents should be tied to observable behaviour, not just calendar-based recertification.

The lifecycle failure patterns are well documented in NHI research, including excessive permissions, offboarding gaps, and poor visibility. The 2025 State of NHIs and Secrets in Cybersecurity and the Ultimate Guide to NHIs, Key Challenges and Risks both reinforce that visibility and lifecycle discipline are inseparable. The scale problem is also real: NHIs are far more numerous than human identities, so manual treatment does not scale cleanly.

Risk and Threat Considerations

When agent identities share lifecycle processes with humans without agent-specific controls, the main risk is stale or overextended authority. Access may survive after the business need changes, and compromised or abandoned agent credentials can continue to operate with no obvious human signal behind them.

Failure mechanism: Human-centric review cycles miss fast-changing tool usage, reused credentials, hidden dependencies, or inactive ownership, allowing excessive or obsolete agent access to persist.

Impact: The result is widened blast radius, harder incident containment, and a higher chance that a compromised agent or forgotten integration can still reach production systems, data, or downstream services.

Standards & Framework Alignment

This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.

OWASP Non-Human Identity Top 10 and OWASP Agentic AI Top 10 define the specific risk controls and attack patterns relevant to this topic.

Framework	Control / Reference	Relevance
OWASP Non-Human Identity Top 10	NHI-01 — Improper Offboarding	Agent access must be revoked when ownership or need ends.
	NHI-05 — Overprivileged NHI	Agent lifecycle review must catch excess permissions and blast radius growth.
	NHI-07 — Long-Lived Secrets	Agent governance depends on rotating credentials that outlive their intended use.
Recommendation — Revoke agent credentials and delegated access when the business process ends. Limit agent permissions to the minimum tools and systems required. Shorten credential lifetimes and rotate secrets on a defined cadence.
OWASP Agentic AI Top 10	ASI03 — Identity & Privilege Abuse	Agent identities need governance when delegated authority can expand or persist.
	ASI10 — Rogue Agents	Durable ownership and inventory reduce the risk of unmanaged autonomous agents.
Recommendation — Constrain agent authority and monitor for privilege drift over time. Track every autonomous agent to an accountable owner and kill unused instances.

Practitioner Guidance

What to prioritise: Put ownership and inventory before refinement. If you cannot name the responsible team, the agent’s execution scope, and the credentials it can use, lifecycle review is already too weak to trust.

What to verify: Confirm that offboarding covers the agent’s secret, token, certificate, and delegated access paths, not just the logical account record. If access can still authenticate after the business process ends, the lifecycle is incomplete.

Decision rule: If the agent can act autonomously or invoke production tools, review it on a shorter cadence than human users and treat behavioural drift as a trigger for recertification, not as a post-incident finding.

Practitioner takeaway: Agents belong in the same governance system as humans and service accounts, but they need stronger discovery, faster review, and explicit ownership because their authority can change faster than traditional identity processes assume.
